Obstetric-related lower back pain: the effect of number of pregnancy on development of chronic lower back pain, worsening of lumbar disc degeneration and alteration of lumbar sagittal balance.

OBJECTIVE: This study aims to determine whether the number of pregnancies contributes to the development of chronic lower back pain, worsening the lumbar disc degeneration and altering the normal lumbar sagittal balance. MATERIAL METHOD: There are 134 ladies participated in this study. They are divided into two groups based on their number of pregnancies (parity). All patients with chronic back pain were assessed using a visual analog scale for pain and the Oswestry Disability Index for their functional status assessment. Degenerative signs in lumbar MRI, which are Modic changes and the presence of Schmorl's node, were evaluated. Besides that, the sagittal balance of the lumbar spine was also measured via an erect lumbar plain radiograph. RESULTS: Patients with parities < 5 were included in Group 1, and those with parities ≥ 5 in Group 2. The mean visual analog scale score of Group 2 was significantly higher than that of Group 1 (8.42 ± 1.34 vs.6.50 ± 1.61). The mean Oswestry Disability Index score in Group 2 was significantly higher than that of Group 1 (29.87 ± 6.75 vs.18.41 ± 7.97). This relationship between the groups in terms of Modic change was statistically significant. The relationship between the groups regarding the presence of Schmorl's nodes was also statistically significant. The difference between the groups in terms of sagittal balance parameters was not statistically significant. CONCLUSION: Chronic lower back pain is significantly worse and associated with more disability in patients with more than five previous pregnancies. MRI degenerative changes are also significantly higher in these grand multipara groups.

Comparison of the efficacy of corticosteroid, dry needling, and PRP application in lateral epicondylitis.

PURPOSE: The aim of this study was to compare the short-term efficacy of dry needling, corticosteroids, and platelet-rich plasma application (PRP) in the management of lateral epicondylitis. METHODS: The study included 72 patients diagnosed with lateral epicondylitis divided into three groups of 24 individuals using the sealed envelope method. Group 1 underwent dry needling, Group 2 received 40 mg methylprednisolone acetate, and Group 3 received PRP treatment. Patients were assessed using the visual analog scale (VAS) and the Disabilities of the Shoulder, Arm, and Hand (DASH) score, and Jamar grip strength before treatment and 3rd week and 3rd month. RESULTS: At the 3rd month, the mean VAS score was 1.16 ± 0.56 in dry needling group and 0.75 ± 0.60 in corticosteroids group, showing a statistically significant difference between dry needling and corticosteroids group, and between corticosteroids and PRP group (p = 0.015 and p = 0.000, respectively). At the 3rd week and 3rd month, VAS scores decreased in each treatment modality group, showing a statistically significant difference between the groups (p < 0.01). Jamar grip strength increased over time in all groups. There were no significant differences between the DASH scores of all groups at the 3rd week (p > 0.05). DASH scores decreased significantly from the 3rd week to the 3rd month in dry needling and corticosteroids group (p < 0.01), while it increased slightly in PRP group during the same period with a statistically insignificant change (p > 0.05). DASH scores decreased significantly at the 3rd month for all groups (p = 0.014). CONCLUSION: Dry needling is an effective and safe application for the short-term treatment of lateral epicondylitis.
